Which of the following is an important difference between light-dependent and light-independent reactions of photosynthesis? 

• The light-dependent reactions occur only during the day; the light-independent reactions occur only during the day.
• The light-dependent reactions occur in the cytoplasm; the light-independent reactions occur in chloroplasts.           
• The light-dependent reactions utilize CO2 and H2O; the light-independent reactions produce CO2 and H2O.
• The light-dependent reactions produce ATP and NADPH; the light-independent reactions use stored energy in ATP and NADPH to produce sugar.

In photosynthesis, sunlight is used as ___. 

• a pigment
• an enzyme
• an energy source
• as raw material

The molecule in the diagram above plays what role in the body? 

• Forming part of the sugar-phosphate backbone of DNA
• Storing and releasing energy
• Storing fat
• Controlling blood glucose levels

What is the correct equation for photosynthesis? 

• 6O2 + C6H12O6 → 6CO2 + 6H2O + Energy
• 6O2 + C6H12O6 + Energy → 6CO2 + 6H2O
• 6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆ + Energy
• 6CO₂ + 6H₂O + Energy → 6O₂ + C₆H₁₂O₆
